Q. What needs to be done or watched for once living gluten free, 4 years in my case, with nothing more than an occasionally accidental ingestion of some gluten? Are there any tests that we should have, assuming everything else appears to be fine?

A. If you are well, then an occasional accidental gluten exposure is safe. Each individual has an unique reaction to gluten depending upon their genetics, the bacterial and viral environment of their gut,and many other factors. To check for inadvertent gluten exposure, get an IgA anti tTG test.
